Jehovah's Witnesses follow the biblical command to "go ye into all the world, and preach the gospel to every creature." Their ability to fulfill this command has been thwarted by municipal regulations restricting or regulating door-to-door solicitation, however. As a result, the Supreme Court has periodically struggled with the balance between a municipality's right to limit solicitation and the jehovah's Witnesses's religious requirement to advocate for their religion door-to-door.
